Homework Help:
Work and Electricity

My book says the electrons must be pushed from the positive to the negative terminal, which means work must be done on the electrons.

I find it a bit confusing. Is the book saying that because we are using the conventional current? Meaning that the positive end of the battery has a high potential and the left end a lower potential hence charge must flow from positive to negative. Then in that case, work would have to be done on the charges (electrons) to make them move against the forces of attraction, since, normally, electrons would move the other way?
